Benefits of technology

[0007]It should be understood that the summary above is provided to introduce in simplified form a selection of concepts that are further described in the detailed description. It is not meant to identify key or essential features of the claimed subject matter, the scope of which is defined uniquely by the claims that follow the detailed description. Furthermore, the claimed subject matter is not limited to implementations that solve any disadvantages noted above or in any part of this disclosure.

Problems solved by technology

The part inventory may increase because of the complexity of the product mix produced in a production environment.
Maintaining a production environment that includes relatively more component options, such as using all lower power motors in a first model in place of all higher power motors, used in a second model, may be undesirable.

Embodiment Construction

[0016]Embodiments of the invention may relate to a truck (or bogie) assembly, a vehicle having the truck assembly, and a method of operating the truck assembly. Vehicles, truck assemblies, systems and / or methods are provided for transferring weight among wheels and / or axles supporting the rail vehicle. As an example, the vehicle may be a locomotive or rail vehicle that can be positioned on a rail.

[0017]In one embodiment, an example method includes operating a vehicle having a suspension. The method may include operating the suspension in a first mode with a first effective suspension spring rate; and operating the suspension in a second mode with a second, different, effective suspension spring rate.

[0018]The suspension may comprise one or more springs, where the one or more springs together have an effective spring rate that varies with displacement of the suspension. In some conditions the rail vehicle selectively, and in some cases dynamically, increases normal force on the rail ...

Abstract

Truck assemblies, systems and methods are provided for transferring weight supported by various wheels, and axles. The vehicle suspension method includes operating the suspension in a first mode with a first effective suspension spring rate; and operating the suspension in a second mode with a second, different, effective suspension spring rate.

Description

BACKGROUND[0001]1. Technical Field[0002]Embodiments of the invention may relate to a truck assembly, a vehicle having the truck assembly, and / or a method of operating the truck assembly, for example.[0003]2. Discussion of Art[0004]The cost of manufacturing vehicles, and the cost of maintaining an inventory of production parts, may increase in accordance with the level of customization of individual vehicle models. The part inventory may increase because of the complexity of the product mix produced in a production environment. Some vehicles may include a front truck and a rear truck with two or more axles on each truck. Each axle may have a motor. In a manufacturing instance where the power required for one vehicle is less than another, the lower powered vehicle may need to be produced with a number of motors of lesser power equal to the number of axles. Distributing the motors among all the axles may improve the wheel traction during use. Maintaining a production environment that i...
